CIRCUIT-CLOSER.

' Specification of Letters Patent.

Patented Aug. 11, 1914.

Application filed October 30, 1913. Serial No. 798,382.

To all whom it may concern:

Be it known that 1, ANDREW Gr. ANDEIP in the art to which it appertainsto make and use the same.

This invention broadly relates to circuit closers but more particularlyto that class of the latter intended to be used in conjunction withsystems employed to electrically light the headlights of automobiles.

One object of my invention is to provide a device of this characteradapted to be used in conjunction with systems employed for electricallylighting automobile headlights and which will enable the driver tocontrol the individual circuits of each lamp.

Another and further object of my invention is to provide a circuitcloser which is simple, inexpensive and readily applicable to the dashboard of any automobile.

With these and other objects in view, my invention consists of certainnovel features of construction, and combination and arrangement of partsas will be more fully described and claimed.

In the accompanying drawings in which similar reference numeralsindicate COII'G', sponding parts, Figure 1 is a diagrammatic viewillustrating the application of my improved circuit closer to anelectric lighting system employed in conjunction with the headlights ofan automobile. Fig. 2is an enlarged front elevation of a portion of thedash board showing the two circuit closers and, Fig. 8 is a verticalsection taken on the line 83 of Fig. 2.

In Fig. 1 of the drawings is diagrammatically shown the construction Ipreferably employ, wherein the automobile A has the usual gasoleneengine E with its magneto M and coil box C and the head lights or lampsL receive their gas from a tank T through a pipe P which in the presentinstance is controlled by a valve V adjacent the hand of the driver. Iwould locate this valve in such position that he may reach it withoutleaving his seat, and the detailed construction of the valve itself isnot important. Obviously the tank might be re placed by an acetylenegenerator or other device for supplying an illuminating fluid to theburners within the lamps. These burners also I need not illustrate, northe electrical gas-lighting devices themselves, as both are well knownin the art.

Coming now to the details of the present invention, I connect a bar 1with one of the secondary wires in the coil box G, and this bar formsone pole of twopush buttons. The other wire 2 from either push buttonleads directly to the lighting device 3 in one of the lamps, whichdevice will have two terminals adjacent the burner, and the otherterminal will be connected with the ground in any suitable way. The wire2 'nected with the lighting device 3 in the other lamp, entirelyseparate from the firstnamed wire. Each push button has a spring tongue4 whose free end underlies the bar 1 and whose other end is secured witha base 5 by a binding post- 6 from which the wire 2 is led. At about itsmidlength the tongue is pierced with a hole through which extends aheaded pin or screw 7 around which is coiled an expansive spring 8. Theupper end of the spring is engaged beneath the head of the pin, and thelower end rests 011 a leaf spring 9 which overlies the tongue 4, and thepresence of this leaf spring as well as of the coil spring gives the tipof the tongue great flexibility. The shank 10 of the knob passes looselythrough a hole in a guard 11 secured to the front face of the base 5,and is then reduced and shouldered as at 12, its smaller end 13 passingthrough a hole 14 in said base and standing over or near the tip of thetongue 4. Said hole is enlarged at its upper portion so as to produce ashoulder 15 within its length, and coiled on the reduced portion of theshank between this shoulder in the hole and the shoulder on the shank isan expansive spring 17. Finally a pin 18 passes through the largerportion of the shank beneath the guard 11 and prevents the expansiveforce of this spring from throwing the shank out of place. As the knobis pressed upon its shank moves through the hole in the guard, theexpansive coiled spring is compressed within the enlarged upper end ofthe hole through the base, and the reduced lower end of the shank isprojected out the lower end of said hole and bears upon the springtongue 4. When now the driver desires to light the lamps, he opens thevalve V to permit gas to pass from the tank T'to the lamps L, and thenhe pushes first one push button and then the other. Closure of eithercircuit causes a spark to jump the spark gap in each lamp, and thelights are ignited at the points 3 and 3. j

From the foregoing it will be seen that I have provided a circuit closerof few parts any of which may be readily replaced when broken or wornand one which can be quickly and conveniently set up wherever desired.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to Without departing from the principle orsacrificing any of the advantages of the claimed invention.

What is claimed as new is:

1. The herein describedduplex push button comprising a base, a baroverlying the base and forming one terminal, a plurality of tongueslying on said base with their free ends beneath said bar, binding postsconstituting the other terminals and securing the other ends of saidtongues to said base, headed pins rising from the latter, the tongueshaving holes loosely embracing the pins, coil springs surroundin'g'thepins beneath their heads, leaf springs overlying the tongues andstanding against the other ends of said coil springs, and knobs whoseshanks are slidably mounted through said base adjacent the free ends ofsaid tongues.

2. The herein described duplex push button comprising a base, a baroverlying the base and forming one terminal, a plurality of tongueslying on said base with their free ends beneath said bar, binding postsconstituting the other terminals and securing the other ends. of saidtongues to said base, headed pins rising from the latter, the tongueshaving holes loosely embracing the pins, coil springs surrounding thepins beneath their heads, leaf springs overlying the tongues andstanding against the other ends of said coil springs, knobs whose shan shave reduced portions passing through said base and standing over thefree ends of the tongues, a guard having holes loosely receiving theshanks beneath the knobs, and pins through said shanks underlying theguard, for the purpose set forth.

3. In a push button, the combination with a base pierced with a holeenlarged at its outer end, a bar underlying the base and forming oneterminal, a spring tongue also underlying the base and having one endoverlying and out of contact with the bar, and a binding post securingthe other end of the tongue to the base and constituting the otherterminal; of a guard overlying the base and pierced with a hole, and aknob whose shank projects loosely through said hole and is shoulderedand reduced, the reduced portion projecting through the hole in the baseand standing over the free end of the tongue, and coiled expansivesprings surrounding said reduced portion beneath the shoulder on thestem and within the enlarged upper end of the hole in said base.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
